Solvothermal synthesis, crystal structure and luminescence of the first organic amine templated europium sulfate

The first organic amine templated europium sulfate [C2N2H10]1.5[Eu(SO4)3(H2O)] · 2H2O (1), has been synthesized under solvothermal conditions by using a mixture of n-butanol and water as the solvent. The colorless block crystals were characterized by IR, TGA and ICP. Crystal structure analysis shows that the corrugated layered framework of compound 1 is constructed from EuO9 polyhedra and sulfate groups, while non-coordination water molecules and ethylenediamine molecules link the adjacent layers by hydrogen bonds. Compound 1 represents a strong luminescence upon the excitation.

The structure of europium sulfates [Eu(SO4)3(H2O)][C2N2H10]1.5 · 2H2O (1), shows that the corrugated layer framework of 1 constructed from EnO9 polyhedra and sulfate groups. Non-coordination water molecules and ethylenediamine molecules link adjacent layer by using hydrogen bonds.
